WRENCH.

Specification of Letters Patent.

Patented Aug. 27, 1907.

Apnlicntim fi June 28, 1907. Serial No. 381,813-

To all whom it may concern:

Be it known that I, ERNEST Rrciuun Blcncknn, a citizen of the United States of America, residing at Etna, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Wrenches, of which the following is a specification, reference being bad therein to the accompanying drawing.

This invention relates to improvements in wrenches, and the invention has for its obj ect to provide a novel wrench wherein a novel locking means is employed for retaining the movable jaw of the wrench inv a liXed position.

My wrench is constructed upon the principle of a monkey wrench, with the exception that the slow adj ustmen t is dispensed with and novel means employed for easily and quickly adjusting the wrench. To this end, I have devised a wrench wherein the locking mechanism is located in the handle thereof and protect-ed from injury that it might receive where the mechanism is exposed, as in an ordinary monkey wrench.

The detailed construction entering into my invention will be presently described, and then specifically pointed out in the appended claims.

In the drawing, Figure 1. is a vertical sectional View of the wrench. Fig. 2 is an elevation of the same, and Fig. 3 is a vertical sectional view of the wrench.

To put :my invention into practice, I construct my wrench of a shank 1. having a fixed jaw 2. The greater part of the shank is rectangular in cross section, while the lower end of the shank is cylindrical, as at 3, and is threaded, as at 4, to receive a detachable cap 5. The shank 1 adjacent to the cylindrical portion 3 thereof has its edges provided with teeth 6, the object of which will presently appear. The upper part oi the shank is graduated, as at 6, whereby the jaw 7 can be moved to a prescribed distance from the fixed jaw 2. Slidably mounted upon shank 1 is a movable jaw 7 having a web portion 8 supporting a strap 9, which embraces the shank 1. Suitably secured to the strap 9 is a plate 10 having a threaded opening 11 to receive a collar 12, the lower end of said collar carrying a peripheral flange 14L. Revolubly mounted upon the collar 12 and retained thereon by the flange 14 is a handle or sleeve 15 carrying an inwardly projecting toothed lock 16 adapt ed to mesh with the teeth 6 ol the shank 1.

In assembling the wrench, the jaw 7 and strap 9 are placed upon the shank prior to placing the cap 5 in position. The flanged collar 12 is then placed in the handle or sleeve 15, held therein by a suitable instrument and rotated into engagei'nent with the plate 10. The cap 5 is then placed in position. This construction permits of a free rotation of the handle or sleeve 15, the moving of the block 16 into mesh with the teeth 6 of the shank 1., and a rapid adjustment ol' the jaw 7 thereby.

The wrench in its entirety is constructed of strong and durable metal, and can be made any desired size.

Having fully described my invention, what I claim and desire to secure by Letters Patent is:

A wrench embodying a shank having diametrically opposed edges provided with teeth, a fixed jaw carried by said shank, a movable jaw mounted upon said shank, a strap carried thereby and surrounding said shank. a plate carried by said strap, a flanged collar threaded into said plate, a handle or sleeve revolubly mounted upon said collar and surrounding said shank, and an inwardly pro jeeting toothed block carried by said sleeve for meshing with the teeth of said shank, and a cap carried by the lower end ot aid shank.

In testimony whereof I ullix my signature in the presence of two witnesses.
